Key features

  • Domestic aramid paper replaces Nomex® to reduce cost in Class F applications.
  • Three-layer construction balances heat resistance, dielectric strength and mechanical strength.
  • Multiple thickness/grammage grades for different motor slot insulation needs.

Applications

Class F motor slot insulation, liners and turn insulation; appliance insulation.
